OILER FOR SPINNING MACHINES.

Application led January This invention relates to an improved construction of oiling device morefparticula'rly adapted for cap spinning machines; and has for its object to provide simple and effective means for oiling the bearing portion of the package carrying tube, as it is rapidly rotated on the spindle, from the oil reservoir which is carried on the lift rail. i i

A further object of this invention is to mount one or more oil pads in the reservoir, one of the pads being in contact with the spindle, and to also provide a lid for the reservoir having an oil-measi'iring recess in .its face and air and oil holes through it communicating with the reservoir below for supplying vboth oil and air to this reservoir to conduct the oil thereto when applied and also to prevent the forming of a vacuum in the reservoir to permit the rapid rotation of the tube to lift the oil from the reservoir and lubricate the spindle and tube throughout the length thereof when it bears upon the spindle.

A still further object of this invention is to concave the under surface of the lower flanged portion on the tube-driving whirl, which portion is arrangedA to extend down into the oil-measuring recess of the lid and cover the oil and vent holes therein to create by its rapid rotation an air pressure and direct the same downwardly through the oil holes to act upon the oil held m the pads 'in the reservoir and assist the rapidly rotating tube to lift the oil upwardly through the pads to lubricate the spindle and the tube during the reciprocating travel of the latter.

lVth these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

into the oil reservoir and also designed to support the whirl and its yarn package carrying tube. n

Figure l shows the oil reservoir as mounted on the lift rail and showing the pads in the reservoir with the lid in position, supporting the package tube whirl. l

Figure 5 is arsection on line 5 5 of Figure 4.

Figure 6 is a side elevation showing a portion of the end of the lift rail with a stop or lug formed on the reservoir cup to prevent relative rotation of the reservoir on the rail.

It is found in the practical operation of cap spinning` machines, very difficult to oil the rapidly ruiming package carrying tube while traversing vertically on its spindle, sufliciently to prevent undue wear even though oil be applied to this old style spindle two or three times a day, and even then portions of the tube become drywhich greatly limits the working life thereof, but by the use of my improved fountain type of oiler the attendant needs only lto apply oil to the reservoir but once in two weeks instead of twice a day, as by the old method, and instead of leaving a portion of the tube dry by this old hand-oiling method any desired amount of oil may be forced up inside the tube to keep the same fully lubricated, which is accomplished by simply changing the shape of that portion of the lower flange of the whirl that sets into the oil recess in the lid member and also by adjusting its vertical position in the recess; also by the 'use ofniy improved oiling device which provides perfect lubrication for the tube, the power required for driving the package carrying whirl is greatly reduced, the wearing life of this mechanism is greatly increased and the tube being so properly oiled will run at a more uniform speed thereby setting a more uniform twistin the yarn and so produce a yarn of a much higher quality and of greater value; and the following is a detailed description of the present embodiment of my invention and showing one construction of voiling device by which these advantageous results may be accomplished y With reference to the drawings, 10 designates the bolster rail of the usual cap spinllil lou

il t) tit) ningmachine. which iarries the spindles 11, and 12 designates the litt rail on which the package drivinic)` mechanism is mounted and uy which this mechanism raised and lowered in the cap 13 to lead the yarn to be wound evenly onto the bobbin 14 as it is raised and lowered in the cap. The package is carried on the tube 15 to which tube is connected the whirl 16 that driven by a belt (not sho-wn) to rotate the saine at a high velocity durinsoil the bobbin winding operation.

.lily present invention provides simple and eii'cctive means ttor lnbri ating the spindle and the inner su '..ce ot the tube which contacts therewith tor the purpose ot reducing` thc driving;` friction ot the tube, to obtain a more uniform twist in the yarn to prolong the operating lite ot the tube, and to reduce the drivingy power to the inininnini. and to accinnplish these advantageous results I have formed a cup-shaped reservoir 17 adapted to rest upon the litt rail 12, the cup being` provided with a central opening'A 9 through which the spindle 1l extends. The side wall et this reservoir beingl provided with a hire1 or lip 1S to set down over the edge olI the litt ruil 12 in the manner illustrated in Figure (i, tor the purpose ol preventinpl relative rotation ot the reservoir cup on the rail. This reservoir cup provided with a lid member 19 which has a body portion 2O arranaed to set down into the reservoir and is recessed at 21 'for the purpose presently described. The lid being provided with a recess or keyway 31 to receive a pin 32 to prevent relative rotation between the lid and cup.

The upper :tace of this lid is recessed as at Q2 to provide an oilE measure to deterniinc `inst the proper quantity ot' oil to be deposited therein at a time. which is required 'tor the` conupn'cte` saturation ot' the three superimposed oil storing pads Q3. -.l and The pads 2B and 2l beine' pret'erably ot a size to entirely till the space in the reservoir while pad *.25 is arranged to contact with the sui-'tace ot' the spindle so as to lubricate the saine during the vertical traverse ot the package Carrying` tube thereon.

This lid nieinber 19 is provided with onel or more holes 26 through its tace communiatingj with and permitting the oil `trono the recess above to drop down and saturate the pads in the reservoir below. The upper central portion of this lid is provided with an 1ip1-stainiiiig shoulder 2T presenting a suitable bt-:arinnl l'or the support of the whirl 28 thereon. which shoulder has a central opening; 32) through which the spindle extends.

The lower portion ot this whirl 28 is provided with an annular iiang'e 29 which eX tends slightly downwardly to project into the oil recess 22 but to run clear ot the bottom thereof and the under side of this flange is concavcd as at whereby a rapid rotation et' thc whirl has a tendency to give the air pressure created in the concaved space beneath, a downward direction so as to force the air with slight pressure through the oil holes 2li to act upon the oil in the pads and torce the saine upward into the pad 2.5 in contact with the spindle to cooperate with and assist the action ot the rapidly rotatingV tube to 'further act upon the oil in this pad 25 and litt the saine up through the tube to the very top thereot and so thoroughly luln'icate the spindle and the tube throughout the entire length ot the latter. ln other words. the traverse of the. tubo on the spindle may be -.t1/ while the length ot the tubo may be t5 and the oil by my improved method will travel to the very top of the `tube and `tully lubricate the saine throughout its entire length.

lt will be noted that by my in'lproved construction the lubricating pad that contacts with the spindle sets up inside ot the lower edge oi the whirl, in close j noxiniity to the point ot' greater-'t strain and greatest triction due to the tension ot' the driving hand on the whirl.

My improved oiling device is extremely simple in cinistruction and is etl'ective in its operation and by its use the spindle and the tube are conipletely lubricated.

It found :in practice by changing the shape oit the concavity ot the under side ot the` flange, and the distance the flange extends into the recess in the lid will vary to ccnisiderable `extent theJ amount ol lubricatinp; oil which will flow up through the tube.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that l reserve the privilege oli resorting to all the nuchanical changes to which the device is sua'eptiblc. the invention being' detined and limited only by the terms o'l the appended claims.
